Abstract

Usage: refers to the packaging technique, in particular to the loading of bulk, poisonous substances with a dust suction, and is aimed at expanding technological capabilities and reducing pollution of the surrounding air. SUMMARY OF THE INVENTION: a device includes a feed hopper, a material supply pipe with a V-trim plate installed inside the latter, and a dust suction pipe. What is new is that the device is equipped with a massive cylinder. The V-shaped plate is equipped with a convex bottom fixed to it. The convex bottom is designed so that the radius of convexity of the bottom exceeds the swing radius of the lower edges of the V-shaped plate. The massive cylinder is mounted on a convex bottom with the ability to roll over the latter, 2 silt.

Description

The invention relates to packaging technology, in particular to the loading of poisonous bulk solids with dust extraction. It can be used when loading etched seeds, pre-chemicals, fertilizers.

A device for loading containers with loaded bulk solids is known, comprising a loading hopper, a substance supply pipe with a diametrically arranged V-shaped plate facing upward, and a dust suction pipe made of elastic material with spacer rings on the inside of the pipe, wherein the substance supply pipe is located inside the suction pipe and has a perforated conical bell, the base of which is bonded to the lower edge of the suction pipe, and a V-shaped plate is provided levers with forks at the ends, covering spacer rings with the possibility of impact with the latter.

The known device protects the ambient air well in the presence of pieces, caking layers (especially when loading mineral fertilizers), etc., inclusions causing vibro-shock processes when they come in contact with the V-shaped plate. However, when loading finely dispersed substances such as pesticides, the vibration resistance of the V-shaped plate is small. As a result of this, the suction pipe is slightly shaken.

The aim of the invention is to expand technological capabilities and reduce environmental pollution.

For this, the known device is equipped with a massive cylinder, the V-shaped plate is equipped with a convex bottom fixed to it, made so that the radius of the convexity of the bottom exceeds the swing radius of its lower edges, and the massive cylinder is mounted on a convex bottom with i

the ability to roll over the last V-shaped plate.

In FIG. 1 schematically shows a device, a vertical section; in fig. 2 - section A - A in fig. 1.

The device comprises a feed hopper 1, a substance supply pipe 2, consisting of telescopic sections, and a suction pipe 3, the feed pipe being located inside the suction pipe. The supply pipe 2 in the lower part has a perforated conical bell 4 and a diametrically located V-shaped plate 5 facing upward. A suction pipe 3 is attached to the outer perimeter of the bell 4 and to the hopper 1, spacer rings 6 are attached on its inside. The suction pipe 3 is made of elastic material, for example, rubberized dense fabric, tarpaulin. The cavity 7 formed by the supply pipes 2, suction 3 and conical socket 4, pipe 8 is connected to a suction and air filtration system. The axis 9 of the V-shaped plate 5 is led outside the pipe 2 into the cavity 7 and is rigidly connected to the levers 10. At the ends of the levers 10 have forks 11, covering spacer rings 6. For reliable operation of the device in the contact zones of the forks 11 with rings 6 to the last rigidly rods 12 are attached, for example, along a chord of a ring. The outer diameter of the conical socket 4 is made tightly adjacent to the loading neck of the container 13. To raise and lower the device, it can be equipped with a lifting mechanism, for example, of a pipe-block type. The V-shaped plate is equipped with a convex bottom 14 fixed thereon, designed so that the radius of the convexity of the bottom exceeds the swing radius of its lower edges. The device is equipped with a massive cylinder 15 mounted on a convex bottom 14 with the possibility of rolling over it. The radius of curvature of the bottom is above (point C) the center of the axis 9. Alternatively, the bottom may be flat. The cavity formed by the formation 5 and bottom 14, after laying the cylinder 15 therein, is sealed by the bottom 16, for example, is welded.

The device operates as follows.

The duct 8 of the suction-filtration system is connected to the nozzle 8 and this system is turned on. The conical socket 4 is lowered and attached to the container 13. The feed substance from the hopper 1 enters the container 13, and the dust generated thereby through the perforation of the socket 4, the cavity 7 and the pipe 8 is sucked. The falling feed material collides with the V-shaped plate 5 causing it to self-oscillate, and at the same time torsional vibrations of the axis 9. The excitation force of self-oscillations is enhanced by the presence of a massive cylinder 15, rolling from one extreme position to the other and colliding with the plate walls 5 Location of the center of curvature bottom 14 above

the center of swing of the lower edges of the plates 5 allows the cylinder to roll from one extreme position to another while the plate 5 is swinging. Torsional vibrations of the axis 9 are transmitted by levers 10

causing vibroshock processes in the pair of plugs 11 — rods 12. Due to the constant force shaking of the supply pipe 2 and the suction pipe 3, the dust does not settle on the surfaces of the cavity 7. A small amount of dust deposited in the cavity 7 is periodically removed from the increase in power suction systems and mechanical tapping outside through the pipe 3.
